问题
I installed Anaconda Python on my machine. When I start the Python Interpreter and type "import caffe" in the Python shell, I get the following error:
ImportError: No module named google.protobuf.internal
I have the following files:
wire_format_lite_inl.h
wire_format_lite.h
wire_format.h
unknown_field_set.h
text_format.h
service.h
repeated_field.h
reflection_ops.h
message_lite.h
message.h
generated_message_util.h
extension_set.h
descriptor.proto
descriptor.h
generated_message_reflection.h
generated_enum_reflection.h
dynamic_message.h
descriptor.pb.h
descriptor_database.h
What files do I need so the import will work? Is there an "internal.h" file that is required?
回答1:
This is probably because you have two python environments in your machine, the one provided by your linux distribution(pip) and the other by the anaconda environment (/home/username/anaconda2/bin/pip).
Try installing protobuf for both environments to be sure
pip install protobuf
/home/username/anaconda2/bin/pip install protobuf
回答2:
If you are using Ubuntu, try installing protobuf using
sudo apt-get install protobuf
It solved the same problem that I faced.
回答3:
If you are using Anaconda, do conda install protobuf
回答4:
Easiest way to fix it:
pip install grpcio
pip install protobuf
回答5:
This is because the python envirnment confusion.
# check where pip2
$ where pip2
/usr/local/bin/pip2
/usr/bin/pip2
# check where pip
$ which pip
/usr/local/bin/pip
On my computer, I have two pip2(I install caffe using python2 env), so I used /usr/local/bin/pip2 install protobuf solved this problem.
/usr/local/bin/pip2 install protobuf
